Abstract:- merce (merce) activities, which make use of wireless transactions to provide personalized and location-based services to users of high-speed mobile devices and works around the world, are getting more and more popular nowadays. Current technologies available for merce applications development such as WAP, J2ME, BREW, .NET Mobile, and embedded database are surveyed and evaluated in the paper; among them J2ME proves to be powerful and instrumental in mobile device programming. This paper serves to discuss and demonstrate the standard approach and techniques in engineering merce applications based on J2ME. The design of application tasks ponents discussed include client modules, screen design, screen flowchart, server and database interfaces, etc. Typical merce applications like Movie Ticket Booking and Travel Planning were developed in the project to illustrate how mobile users browse and mon consumer items (movie tickets, tour packages, etc.) online through their Personal Digital Assistant (PDAs) or mobile phones. More advanced application features include checking the validity of the credit card number, and storing the transaction details locally that users can view anytime late
